Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings of the description.
[0032] The design of the reflector involves two parts of energy distribution, one part is the energy directly emitted from the lamp, which is called direct energy E z , the other part is the energy reflected from the lamp by the reflector, called the reflected energy E f , the part of the light emitted directly irradiates the target surface to form an initial rectangular lighting area, and the function of the reflector is to reflect the rest of the energy into this initial lighting area, so that the two parts of energy are superimposed to form a uniform lighting area.
[0033] The main design method of the reflector cup of the present invention comprises the following steps:
[0034] (1) if figure 1 is the spatial coordinate system of the LED light source, with the LED light source as the coordinate origin, and the θ angle is the angle between the ...
