LED lamp

Abstract

The invention relates to a lighting appliance, and discloses an LED lamp which comprises a lampshade and a base connected with the lampshade, a photoelectric module is arranged in a first containing space formed by the lampshade and the base, a light source module comprises a light source module and a power module, the light source module comprises a first chip area and a second chip area, and a part of the power module is located between the first chip area and the second chip area. The LED lamp has the advantages of being thin in thickness, excellent in light-emitting effect and good in heat dissipation performance.

Description

technical field [0001] The present application relates to a lighting appliance, in particular to an LED lamp. Background technique [0002] Ceiling lamps are lighting fixtures that are absorbed or embedded in the roof ceiling. They are often used as lighting equipment in various places such as homes, offices, and entertainment venues. A traditional ceiling lamp usually consists of a base, a light source module, a circuit module and a lampshade, and the light-emitting elements in the light source module are generally energy-saving lamps. Since energy-saving lamps are polluted by mercury in the production process and after they are used and discarded, and their power consumption is larger than that of LEDs, while LEDs have the characteristics of no mercury, no toxicity, no electromagnetic pollution, no harmful rays, energy saving, environmental protection, and long service life. Therefore, the light-emitting elements of ceiling lamps gradually replaced energy-saving lamps wit...

AI Technical Summary

Problems solved by technology

[0003] 1. Flickering occurs during lighting, small irradiation range, uneven light emission, small brightness in the central part of the lamp, uneven brightness between the central part of the lamp and the peripheral part of the lamp, uneven light emission on the light emitting surface, glare, uneven brightness around the lamp, and luminescence Uneven illumination on the component mounting surface, uneven brightness and low color rendering, low luminous efficiency and light design, bright spots, low rendering effect, uneven color mixing, uneven illumination around the ceiling, and high height circuit components Will block light, large color temperature and color deviation, narrow light orientation, low light transmission efficiency, low luminous efficiency of light source, dark side area of ​​lampshade, uneven brightness of light exit surface of lampshade, bright lines, light-emitting elements Low light extraction efficiency, low light comfort, low aesthetics when extinction, etc. In addition, the existing lamps will also have the following problems: some use scenarios will hope that the light emitted by the lamps has a three-dimensional effect or corresponding to the corresponding life scene. It is difficult for users to read under the lamps and lanterns, or because the color of the text and the object of observation is reduced by the elderly, the elderly have a low sense of comfort when using light, etc.

[0004] In order to improve the optical effect of the ceiling lamp, one of them is to add a backlight lens to the LED to reduce the dark area in the middle and edge of the lamp. However, due to the use of the backlight lens and lens patch technology, the production cost is greatly increased and the product competition is reduced. Second, optical components, such as light guide plate, lens, reflection unit, etc., are arranged between the light-emitting element and the lampshade. , Uneven brightness on the light guide plate, dark parts on the light guide plate, etc.;

[0005] 2. Light-emitting components and circuit components will generate heat, which will affect the service life of the ceiling lamp;

[0006] 3. Most of the light source modules are installed in the lamp body by screws, or pasted in the lamp body by adhesive, and it is not easy to disassemble and replace after installation

In addition, after long-term use of the ceiling lamp, the aging and burning of the light source module often occur. Installation and replacement of LED light source modules must be performed by professionals, which is inconvenient to use;

[0007] 4. Ceiling lamps are usually flat structures, with the characteristics of small occupation height and wide lighting range. However, the overall thickness of ceiling lamps is still large, resulting in increased product volume, which in turn increases packaging and inventory costs.

[0008] In addition, the lamps have low safety, low manufacturing efficiency, high cost of use, insects, etc. are easy to enter the interior of the lamp and affect the appearance, and cannot continue to illuminate when the power supply fails. Limit, low remote control sensitivity or narrow remote control range during intelligent control, noise during installation, etc.
